Heat Transfer Leidenfrost point is a term concerned with the Boiling of a liquid on a hot surface Heat transfer between two highly viscous liquids Concentration of a corrosive solution by evaporation Condensation of the saturated vapor on a cold surface Boiling of a liquid on a hot surface Heat transfer between two highly viscous liquids Concentration of a corrosive solution by evaporation Condensation of the saturated vapor on a cold surface ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer A dilute aqueous solution is to be concentrated in an evaporator system. High pressure steam is available. Multiple effect evaporator system is employed, because Total heat transfer area of all the effects is -less than that in a single effect evaporator system Heat transfer co-efficient in a single effect is much lower than that in any effect in a multieffect system Total amount of vapor produced per Kg of feed steam in a multiple effect system is much higher than in a single effect Boiling point elevation in a single effect system is much higher than that in any effect in a multieffect system Total heat transfer area of all the effects is -less than that in a single effect evaporator system Heat transfer co-efficient in a single effect is much lower than that in any effect in a multieffect system Total amount of vapor produced per Kg of feed steam in a multiple effect system is much higher than in a single effect Boiling point elevation in a single effect system is much higher than that in any effect in a multieffect system ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Heat transfer by conduction results due to the transfer of free electrons, kinetic energy & vibrational energy from one molecule to another. Conduction heat transfer can not take place Between two bodies in physical contact with each other Between two bodies not in physical contact with each other Both B & C From one part of a body to the another part of the same body Between two bodies in physical contact with each other Between two bodies not in physical contact with each other Both B & C From one part of a body to the another part of the same body ANSWER DOWNLOAD EXAMIANS APP
